Specification of Letters Patent.

Patented Nov. 6, 1906.

Application iiled July 31,1902. Serial No. 117,781.

To all whom it may concern:

lBe it known that l, ALFRED H. HUMPHREY, a citizen of the United States,residing at the city of Kalamazoo, in the county of Kalamazoo and Stateof Michigan, have invented certain new and useful m rovements in Gas- Burners, of which the fol owing is a specification.

This invention relates to improvements in gas-burners.

It relates particularly to an improved construction of burners known asHclusterburners."

The objects of the invention are, first, to provide an improvedcluster-burner in which a cluster of burners is embraced by a singleglobe for protection, without the necessity of using chimneys second, toprovide in a cluster-burner improved means for supporting a globe sothat the same can be readily attached or removed or adjusted, asdesired; third, to provide'an improved construction of burner-base andcontrolling-valve; fourth,

valve for the burners for regulating the delivery of gas and completelycontrolling the same.

Further objects will definitely appear in the detailed description tofollow.

l accomplish the objects of my invention by the devices and meansdescribed in the following specification. V

The invention is clearly defined, and pointed out in the claims. o

A structure embodying the features of my invention is fully illustratedin the accompanying drawings, forming a part of this specification, inwhich'- Figure 1 is aview, partially in section, taken on a linecorresponding to line 1 1 of Fig. 2, showing the arrangement of theparts. Fig. 2 is an enlarged detail cross-sectional View taken on line 22 of Fig. 1. Fig. 3 is an enlarged vertical detail sectional viewthrough one of the burners and the central mantle-support, taken on aline corresponding to line 3 3 of Fig. v2. Fig. 4 is an enlarged detailview of one of the single-burner bases B, showing the method ofconstructing the same.

In the drawings all of the sectionalviews are taken looking in thedirection of the little arrows `at the ends of the section-lines,andsimilar letters of reference refer to similar parts throughout theseveral views valve b extends. Aed to fit into a suitable threadedperforation arts of the drawet, to which the Referring to the letteredings, A is the central brac remaining parts -are secured. This ishollow.

and contains the valve J for regulating the passage of gas. The bracketA is adapted to be secured to a suitable gas-supply, depending piece ofgasipe Extending out radialfy from the lower part. `of the main bracketA are tubular arms B,

which terminate in balls B at their outer ends, which are partially cutaway on the upper side and formed into threaded nipples e. Nozzles I areadapted to be secured to the nipples e. These are provided with anupwardly-projecting art having a central perforation into which) thepoint of the needle- This valve is screw-threadin the bottom of the ballB and 1s provided with a suitable knurled head for manipulation. Acoiled spring b is provided to put tension on the screw to prevent itsaccidental dis lacement.

vto provide an improved adjustable supplyt will be observed that thisneedle-valve yrequires very little adjustment and that a.

new nozzle loan be readily substituted when ,a larger orsmaller passageis desired, as it is found desirable to have the passage as nearlyunobstructed as possible to deliver a strong central jet to secure thebest results.

Secured to the nozzle is an upwardly-ex- .jtending mixing-tube G, whichis provided with suitable apertures G Afor the admission of air.

toward its bottom The tube G is preferably tapered upwardly, and securedto its upper end by a suitable slip-joint at c is a suitable burner-tipholder H.

Projecting' downwardly from the or coupling A bracket is 'a pin C,having an annular groove C. This aords a support for the globe-holder.The globe-holder consists of -a collar D, adapted to be slipped upon thepin C, and this is provided with a set-screw a., adapted to engage inthe groove C to retain the collar adjustably in position.

Outwardly and upwardly projecting arms D are secured to the collar, andon the top of these arms is a globe-holder or band E, to which the globemay be secured by suitable set-screws.

Supported by radial arms s on the collar s on the central pipe A is aband or ring S of corrugated metal, which the top of the globe F engagesand which guides the same and retains it in position. This band Sconforms t0 as the IOO ' 4band F, which is secured in the globe andforms port therefor. The many points of contact to the metal absorb theheat from the globe and equalize the same and prevent the breaking ofthe globe.

On top of the globe F is an ornamental position by suitable set-screws.

I have illustrated and described my invention in the form preferred byme on account of the simplicity and economy of manufacture andconvenience in use. I am aware, however, that it is capable ofconsiderable variation in structural detailswithout departing from myinvention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is`

1. In a cluster-burner, the combination of a central bracket havingradial arms with suitable burners toward their outer ends; a pin Cdownwardly depending from said central bracket, containing an annulargroove C; a globe-holder consisting of a globe-supporting band E withdownwardly-extending arms D', curved slightly outwardly, thenceinwardly; a collar D to which the lower ends of said arms are secured,and a suitable thumbnut on said collar adapted to engage the said grooveC', whereby the globe-holder and its attached globe can be readilyadjustedand secure-d vin position, or removed as desired Withoutdisturbing the burners, as s peciied.

2. In a; cluster-burner the combination of a central bracket havingradial arms with suitable burners toward their outer ends 3 a pin Cdownwardly depending from said central bracket, containing an annulargroove C', a globe-holder consisting of a globe-supporting band E withdownwardly-extending arms D/ curved slightly outwardly, thence inwardlya collar D to which the lower end of said arms are secured, and asuitable thumb-nut on said collar adapted to engage the said groove C,

a perfect guide and supi whereby the globe-holder and its attached globecan be readily adjusted and secured in position, or removed as desiredwithout disturbing the burners; and a guide for the top of the globeabove the burners, as specified.

3. In a cluster-burner the combination of a central bracket havingradial arms; suitable burners on said radial arms; a `)in down- Wardlydepending from said central bracket; a globe-holder consisting of acollar movably 'secured to the said central pin; outwardly and upwardlycurved arms secured to said collar, and a suitable globe-supporting ringsecured to their upper ends, for the purpose specified.

4. In a cluster-burner the combination of a central bracket havingradial arms; suitable burners on said radial arms; a pin down- Wardlydepending from said central bracket; a globe-holder consisting of acollar movably jsecured to the said central pin; outwardly and `upwardlycurved arms secured to said collar; a suitable globe-supporting ring se-(cured to their upper ends, and a guide S for the top of the globe abovethe burner, as specified.

5. In a cluster-burner the combination of a group or cluster of burners;a depending lshank or stem below the same; a globeholder surrounding thecluster and connected to a suitable collar for attachment to the centralshank or stem; an upper globe-support consisting of a ring of corrugatedmetal which the said globe embraces to accommodate the expansion andcontraction and to equalize the heat on the globe as specified.

In witness whereof I have hereunto set my hand and seal in the presenceof two witnesses.
